find the general solution for y''[x] = -y'[x]
the answer is y=c1e^(tx1) + c2e^(tx2) where c1, c2, x1, x2 are separate variables/constants...
i don't understand..i keep getting that y=ce^-x but that comes nowhere close to what the real answer is?
If anyone can help me, I would greatly appreciate it (ie worship them forever)
Thanks
ps. should this go in the diffeq forum? i wasn't sure because this is basic diffeq you learn in calc...
The general solution is, as you have already been told, (it is your choice to use t or x as the independent variable since it is not given in the equation). My point is that this is exactly of the form with and .
We will forward you an address to send your tithes to. You will have to purchase your own white robes.If anyone can help me, I would greatly appreciate it (ie worship them forever)
